Application niedfaugust 22,1912. Samira-'natia' a receptacle which will be. durable and re main liquid-tight after severe usage.

Steel barrels, as previously constructed, have been provided with reinforc-ing chimes, but these structures have depended` upon the closeness and' rigidity of engagement thereby, for maintaining the joints atfhe heads. Moreover, in the prior structures, a severe blow upon the head or chime was liable to open or spring the joint or scam,

between the head and body of the barrel,

thereby causing leakage. Accordingly, I have sought to remedy these defects:

First, by making a liquid-proof, doublelocked joint between the head and barrel body, independent of the reinforcing means.

Second, I have provided an auxiliary seal, in the form of a plastic cement, inserted within the annular seam or double-locked joint, preferably employed at the heads of the barrel.

Third, I have provided a peculiarly shaped wrought iron ring, having a protective overturned lip and an annular recess. Within this annular recess the upturned rims of the head and barrel-body are yadapted to be rolled, adjacent to the head, for tightening ceive pressure from within or without the barrel.

Fourth, my improved barrel preferably is provided with two centrally positioned an; nular ribs, than Ithe chimes of the barrel, and forma vbilge whereon said lbarrel is adapted to roll. Further details of my improved construction may be more readily explained, by making reference to the' accompanying drawings, wherein Figure 1, is a side view,

away, illustrating a sheet metal-barrel embdyling my improvementhave' invented certain new of sheet steel with lpurposes whatsoever, and

'imperfections in the against the head, in position to re-' -rings afford substantially f Obviously, any leakage,

which are' of greater diameter- -gasolene and the like, may be at once located sectionally broken 'barrel-head and barre v Fig. l2, is an enlarged vdetail view, showing the annular jouit, 1n section, sertedinteriorly l lar view,showing the flange depressed, and Fig. 4, isanother similar view showing .a section of the completed joint.

Throughout, the figures lof the drawings, I have employed thev same'character of reference to indicate similar parts.

It will he understood that the sheet metal barrel, herein shown, is typical merely, of the structural 'features of barrels, containing-drums or metallicA receptacles for any articularly those requiring a hermetic seal, 0r avoiding lbsscs through evaporation and leakage.v yThe vbody portion a is of substantially cylindrical with the protective rim in- Y thereof. JFigx, isla Simials form; being-'constructed from'sheet-metal of suitable gage, and provided with circumferential spaced ribs a a', forming the bilge of said barrel. disks b b having upturned rims of Such diameter as ,to-fit, snugly within vthe ends of the body por-tiolL, The edges of said body portion first receive a coating of any suitable plastic cement, such as rubber, guttapercha or glue co ositions, and doublelocked joints bi are ormed, embracing both edges and affording four thicknesses of metal :at said joints. Any inequalities or joint, will, of course, be rectied by the cement c, which fills the'mi-` nute spaces 'between the surfaces and edges of the sheet metal. Wrought iron rings d d are then forced down, with their bases d d resting upon the heads b b, and their"y flanges d d. are then bent over the double-locked joints, so as to Vform reinforced chimes for the barrel. It will be observed, that said walls for the double-locked seams, which are left open for inspectiofn, by' providing anges which partially inclose the edges. even with light oils,

and remedied in the construction shown,

without impairing the efficiency of the reinring in place, and

inner vertical face,

. adjacent to the base d', the annular groove d2. Y The bodies of the projectixlilg rims1 ofthe are t en ro ed in parallel engaginghead of the barrel, i

The heads comprise convex the said groove d2, which serves to tighten the ring Withinthedhead, and maintain it rigidly in position. The ange al may be simultaneously or subsequently rolled, if desired, to tighten the same over the doubleloclred joint. Urdinarily, a joint o this character would be sucient for maintaining a seal of the barrel-head, but with heavy gage metal, and particularly in vievv of the re-rolling operation, if said joint has been sprung, it is desirable that a plastic seal be provided in addition, whereby any iin-naediate or subsequent strains of the joint, if or minor character, will be provided for, in'- stead of depending upon a nietai-to-metal, or soldered joint.v

By reason' of the supporting ribs a a', aforded tor the barrel, when itis rolled, the seams at the' heads are not subjected' to any strains from this source.

Having now described with some detail, a steel barrelv eXexnpliying and embodying my invention, ll claim' as new and desire to secure by Letters Patent, the following l. lin a permanent closure for metallic receptacleathe combination with a substantially cylindrical body-portion formed of sheet-metal, of a disk-like sheet-metal closure-member inserted Within the end of said body-portion; the same having an upturned rim with its edges united with the edges of the body-portion to form a double-locked joint, and a protective ring inserted Within said closurefrnember having a down-turned fange covering the side of the double-locked joint, and a continuous annular recess Wherein the rims of said closure-member and-bodyportion are forced, substantially as set forth.

2. lin a sheet-metal barrel, the combinarastreo tion'with a substantially cylindrical bodyl portion formed of sheetmetal and centrally ribbed to provide a bilge, of disk-like sheetl metal heads inserted Within the ends of said body-portion; the same having upturned rims with their edges united With the edges of the body-portion to form double-locked annular joints, and supporting rings inserted Within the rirns to bear annularly against the heads, each of said rings having a' flange partially inclosing the corresponding double-locked joints and continuous annular recess Wherein the rims of the head and barrel Vare rolled or depressed to lock the parts closely together, substantially as set forth.

3. ln a permanent closure for metallic receptacles, the combination with a substan` tially cylindrical body-portion formed o' sheet metal, of disk-like sheet metal closuremernbers inserted Within the ends oi said body-portion; the same having upturned l CHARLES T. DEALER.
